Figuring out the system baseline for memory and cpu usage would be a
good idea. What does it look like under heavy load? What users
typically run what processes? Who is your most 'prolific' user? Who
is the guy who always writes code that makes things thrash? Be able
to look at the box at any given time and be able to tell in under 1
minute that 'something is wrong'.
The other thing that I feel is very important: What is your disaster
recovery plan? Is it written out in a policy? If not, do so. Plan
for everything from "Bob overwrote my file" to FBI/Thieves come in and
literally take your box and all your backup tapes on site. Having it
written down sounds hokey, but when the shit hits the fan it really
helps you to not panic, which everyone knows is Rule #1. Plus your
boss will probably like it, and you'll probably be doing it at your
next job also.

I dreamed of Moses. He wanted to put my hair into cornrows. I said,
"I thought you were born way before those came into fashion?" He
said, "Don't be silly, your dreams never follow the chronology of
history and the purpose of dreams is still quite a mystery even to
So I pulled up a lawn chair, took off my sword and shield and I laid
'em right down there. He braided my hair in the shade of a bare
branch of a beautiful sycamore tree.
And when Moses finished he stared at me hard with a squint and a
grimace said "You look so damn good that I'm mad this isn't real life
and it's just a dream."
